Wearable sensors are evolving from watches and electrodes to bendable devices that provide far more precise biometric measurements and comfort for users. Now, an international team of researchers has taken the evolution one step further by printing sensors directly on human skin without the use of heat.
Led by Huanyu "Larry" Cheng, Dorothy Quiggle Career Development Professor in the Penn State Department of Engineering Science and Mechanics, the team published their results in ACS Applied Materials & Interfaces.
Cheng and his colleagues previously developed flexible printed circuit boards for use in wearable sensors, but printing directly on skin has been hindered by the bonding process for the metallic components in the sensor. Called sintering, this process typically requires temperatures of around 572 degrees Fahrenheit300 degrees Celsiusto bond the sensor's silver nanoparticles together.
"To get around this limitation, we proposed a sintering aid layersomething that would not hurt the skin and could help the material sinter together at a lower temperature."
By adding a nanoparticle to the mix, the silver particles sinter at a lower temperature of about 212 F (100 C).
The room temperature sintering aid layer consists of polyvinyl alcohol pastethe main ingredient in peelable face masksand calcium carbonatewhich comprises eggshells. The layer reduces printing surface roughness and allows for an ultrathin layer of metal patterns that can bend and fold while maintaining electromechanical capabilities. When the sensor is printed, the researchers use an air blower, such as a hair dryer set on cool, to remove the water that is used as a solvent in the ink.
The sensor remains robust in tepid water for a few days, but a hot shower will easily remove it.

Oh, this has absolutely NO Mark Of The Beast stuff going on. NO NO NO!
Is there an End Times ping list?
What SKIN ?
Article fails to say what area of your skin gets this neat little sensor.
My first thoughts were an elbow or knee or finger but those areas would probably have no need of measuring anything .... then I of course thought of my nether parts.
At 70, my wife would probably like an alarm to ring if there was anything worth paying attention to.
Article is vague but thx for the post.
LOL. I wonder if folks thought the first pacemaker was “the mark of the beast”? Implanted blood pressure sensors and defibrillators? Is Rush Limbaugh’s cochlear implant satanic?!? Everything new is the mark of the beast, or proof of the end times.
Well there you go. Huh. Missed the picture. Not the first time. Thx.
Don’t sinter my skin, bro!
If the mark of the beast washes off in warm water, that is a pretty wimpy beast.
Get yer vaccine tattoo, tracking device, amazon alexa, and credit card all in one.
The Mark Of The Wimpy Beast.
By adding a nanoparticle to the mix, the silver particles sinter at a lower temperature of about 212 F is tepid? Water boils at sea level at 211F
So you get have to have 3rd degree burns?
Don’t they now have an injected monitor for blood sugars levels?
Had gestational diabetes. Sticking my finger 10 times a day. Ugh. Luckily it didn’t stick around.
But if it did, I would have went for a monitor.
No thanks

One prick of a small needle twice a month in the back of my arm, above the elbow, as opposed to 150 to 200 finger pricks per month.
You betcha, I wear a sensor.
A minister, a rabbi and a priest sinter up to a bar...
It seems more like either sensors for medical measurements, like body temperature, blood oxygen content or pulse, or to detect and send out nerve impulses for prosthetic limbs. It doesn’t help that the pick-up shown looks more like the make-up for Seven of Nine than anything normal people would actually wear.
